Absorbent material on a nonwoven fabric basis

Abstract

The invention relates to an absorbent material on a nonwoven fabric basis, consisting of a fibrous gauze preferably having a longitudinally oriented initial fiber position, which is solidified by mesh formation while obtaining a three-dimensional fiber order. Furthermore, a fiber pile layer having a mainly vertical fiber orientation is formed, wherein the fiber pile layer has largely preponderantly a loop shape in a manner avoiding fiber tear-out. The material is in particular suitable for being used as a paint roller covering or dye-feeding roller, i.e. for applying liquid substances onto surface structures.

1 . An absorbent material on a nonwoven fabric basis, consisting of a fibrous gauze preferably having a longitudinally oriented initial fiber position, which is solidified by mesh formation while obtaining a three-dimensional fiber order,
 characterized in that   the fiber pile layer having a mainly vertical fiber orientation is formed, wherein the fiber pile layer has largely preponderantly a loop shape in a manner avoiding fiber tear-out.   
     
     
         2 . The absorbent material on a nonwoven fabric basis according to  claim 1 ,
 characterized in that   a mesh layer and a fiber pile layer are provided.   
     
     
         3 . The absorbent material on a nonwoven fabric basis according to  claim 1 ,
 characterized in that   a mesh layer is provided on both sides of the fiber pile layer, wherein the pile layer surface is additionally intermeshed in this respect, and the respective mesh layers have different density or porosity.   
     
     
         4 . The absorbent material on a nonwoven fabric basis according to any one of the preceding claims,
 characterized in that   a rear coating of a thermoplastic or thermally cross-linkable material is provided.   
     
     
         5 . The absorbent material on a nonwoven fabric basis according to any one of the preceding claims,
 characterized in that   the pile height is in the range from 7 to 25 mm, preferably in the range from 4 to 22 mm.   
     
     
         6 . The absorbent material on a nonwoven fabric basis according to any one of the preceding claims,
 characterized in that   the fiber mixture contains binding fibers from substantially 5 to 20% by mass.   
     
     
         7 . The absorbent material on a nonwoven fabric basis according to any one of the preceding claims,
 characterized by   its use as a covering for devices for applying liquids onto arbitrary surface structures.   
     
     
         8 . The absorbent material on a nonwoven fabric basis according to  claim 7 ,
 characterized in that   the covering is formed as a paint roller covering or a dye-feeding roller covering.   
     
     
         9 . A method for producing an absorbent material on a nonwoven fabric basis according to any one of the preceding claims,
 characterized in that   an initial fiber mixture is laid as to form a fibrous gauze, subsequently, a densification is performed by means of mesh formation and unilateral fiber pile formation, wherein the obtained fiber pile layer preponderantly is realized in the form of loops.   
     
     
         10 . The method according to  claim 9 ,
 characterized in that   during the solidification, a base web is supplied in order to increase the final solidity and dimensional stability.   
     
     
         11 . The method according to  claim 9  or  10 ,
 characterized in that 
 an additional mesh formation of the fiber pile layer surface is performed, wherein this additional mesh formation results in a more open structure as compared to the primary mesh formation. 
 
     
     
         12 . A paint roller covering or dye-feeding roller covering, comprising a pile fiber nonwoven fabric, in which a part of the pile fibers has a vertical orientation and a loop shape.
